Answer:
The cell membrane is a single layer of phosphate molecules and lipids. The cell membrane is a double layer of phosphate molecules and lipids. The cell membrane has protein channels that are partly inside and partly outside the cell. The cell membrane has protein channels that are entirely inside the cell.
Explanation:
Homologous pairs separate in meiosis _________, and sister chromatids separate in meiosis _________.
Answer:
Meiosis I
Meiosis II
Explanation:
Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II.
In meiosis II, these chromosomes are further separated into sister chromatids.
Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.
In what way would bacteria that require a pH of 11 for
growth respond to being placed in an environment with a
pH of 2?
Answer:
Explanation:
If the bacteria is required to be in highly basic conditions, putting it in highly acidic conditions would disrupt the internal functions of the bacteria which tends to kill the bacteria.
The way that bacteria that require a pH of 11 for growth respond, replaced in a pH of 2, will respond in the way: the bacteria must be in extremely basic circumstances, exposing it to excessively acidic settings will disturb its internal functions, eventually killing it.
What is pH?The optimum pH for bacterial growth may differ. Some bacteria, known as acidophiles, can thrive in an acidic environment, while others, known as alkalinizes, can grow in a base environment, and the remainder, known as neutrophils, can grow in a neutral pH environment.
Bacteria can keep their internal pH stable by creating acid, base, or buffer. If the surrounding pH is too acidic, the bacteria can produce a base to reduce the H+ concentration. If the conditions are excessively alkaline/basic, the bacteria can make acid through fermenting.
Therefore, Bacteria that require a pH of 11 for growth will respond in the following manner: the bacteria must be under extremely basic circumstances; exposing it to highly acidic settings will disrupt its internal functions, finally killing it.

Answer:
D is the correct answer. (please give me brainliest?)
Social sciences are the disciplines that study human social behaviour or institutions and the functions of human society in a scientific manner. So the correct option is D.
What is the importance of social science?
A collection or a group of disciples related to academic disciplines focusing on the behaviours of the individuals within society is called social science. It is the explanation of the working of the society which explores various aspects from economy to psychology.
The study of social science is relatively new in the field of scientific study. It gained popularity in the 20th century. Advertising, economics, psychology, teaching, managing etc are only some of the fields relied on social science.
The people who study social science are called social scientists. They rely more on the interpretation of the information and qualitative aspects of the methodology of methodologies.
The study of social sciences is important as they help in understanding the behaviour and motivations of the people in the world around us. It also helps in self-awareness.
Therefore the correct option is D.

Based on the images taken through Stella’s microscope, which cell structures could be clearly identified using a compound microscope?
Answer:
Use 400 x in order to study the structure clearly.
Explanation:
Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.
The nitrogen base pairs in the DNA molecule are adenine and or cytosine and .
The nitrogenous bases Adenine form two hydrogen bonds with thymine and the cytosine form three hydrogen bonds with the guanine. Simply, A combines with T and G combines with the C. It is often called as a complementary base pairing because of each base pair bonds only with its specific complementary base partner in a DNA molecule.
The nitrogenous bases Adenine form two hydrogen bonds with thymine and the cytosine form three hydrogen bonds with the guanine.
What are Nitrogen bases?A combines with T and G combines with the C. It is often called as a complementary base pairing because of each base pair bonds only with its specific complementary base partner in a DNA molecule.
The creation of nucleotides, which in turn create the nucleic acids like DNA and RNA, uses a set of five nitrogenous bases.
The sequencing of these bases in DNA and RNA is how information is stored, making them of utmost importance. The nucleotides A C U G are represented by the letters that make up the codons in the genetic code.
Therefore, The nitrogenous bases Adenine form two hydrogen bonds with thymine and the cytosine form three hydrogen bonds with the guanine.

Answer:
The correct answer is: trilobite.
Explanation:
Trilobites were the most common form of early sea life found in Oklahoma. Trilobites were arthropods that are now extinct. This marine species is thought to have lived during the early Cambrian period and they existed for almost 300 million years, before disappearing at the end of the Permian in the Permian-Triassic extinction event.

Bryozoans are a species of seaweed-like aquatic invertebrate animals that have lived since the early Ordovician period.
The Apatosaurus was a herbivore dinosaur that lived in North America during the Jurassic period. They had very long necks and were related to the Brontosaurus.
How do organisms use oxygen
Organisms that use oxygen need it for cellular respiration, in which energy is released from glucose. Energy is needed by the organism for growth, mobility and reproduction.
Answer: Almost all living things need oxygen. They use this oxygen during the process of creating energy in living cells... Animals form other half of the oxygen cycle. We breathe in oxygen which we use to break carbohydrates down into energy in a process called respiration.

How does the acidity of acid rain compare to the acidity of natural rainwater
Answer:
The acidity level of water is measured by the pH scale. Pure water has a pH of 7, which is neutral. However, natural rainwater actually has a pH of 5.6 because it gets exposed to the gases in the atmosphere, making it a bit acidic. True acid rain will have a pH level measuring from 5.0-5.5.
